These examples are programmatically compiled from various online sources to illustrate current usage of the word 'atomic clock.' Any opinions expressed in the examples do not represent those of Merriam-Webster or its editors. 2022 In quantum mechanics, the concept of time itself is deeply complicated, said Jun Ye, a physicist who created the world’s most precise atomic clock, a project of the National Institute of Standards and Technology and the University of Colorado Boulder. The atomic clock shows the most accurate time and frequency standard known and are used as the primary standard for international time distribution service. 2022 Using data from the International Earth Rotation and Reference Systems Service, says 2020 boasted 28 of the world’s shortest days on record since the introduction of the atomic clock in the 1960s made the measurement more scientifically accurate. At present, most of the space-borne atomic clocks used by the major global navigation satellite systems include rubidium atomic clocks, passive hydrogen. The secret to this impeccable precision is the correct measurement of the second as the base. ![]() 2023 An atomic clock based on a fountain of atoms. Atomic clocks deviate only 1 second in about 20 million of years. Order on PMT Online with 0 Finance Available and Reliable Next Day Delivery/Collection near you. 2023 Technically, the ideal measure of time would come from an atomic clock in the vacuum of space, where there’s essentially no gravity. Check out the Antelope Audio 10MX Rubidium Atomic Clock. 2023 The sensors’ accuracy at measuring time makes atomic clocks inside many GPS satellites tick–literally. These are sometimes marketed as 'atomic clocks', but we recommend that they be referred to as 'radio-controlled clocks'. 2023 The second is defined by a process that occurs in the nucleus of a cesium-155 atom-a process that atomic clocks can calculate with stunning accuracy. There are many commercial manufacturers who make clocks that receive time signals from NIST radio station WWVB. ![]() Also known as radio controlled, these atomic movements are the most accurate clock movements on the market today. time in Fort Collins, Colorado up to 5 times per day. 2023 But instead of figuring out a unique time zone for the station, scientists rely on Coordinated Universal Time, or UTC, which is reportedly based on atomic clocks. Our popular Atomic Clock Movement auto-synchronizes with the official U.S. ![]() Tom Vanderbilt, Harper’s Magazine , 13 Mar. Recent Examples on the Web By 1949, the first atomic clock was up and running.
